Adjective Comparison

The comparative form of an adjective takes the ending -er.
The superlative form takes the ending -st. In most cases the word am (or a definite article) precedes the adjective and a further ending is added:

There are some adjectives which have no comparative or superlative forms, such as tot (dead), lebend (alive). The same applies to most of the participles: geschrieben (written), gelesen (read), gegessen (eaten).

in the basic form: (eben)so … wie…(English: as … as …) in the comparative form: als(than)

Dieses Haus ist so hoch wie das andere– This house is as high as the other.Dein Haus ist höher als meines – Your house is higher than mine.

In the superlative grade we often use in or unter (“among”) to express comparison relating to a group:

Johann ist der klügste in der Klasse.(Johann is the most clever in the class.)Dieses Haus ist das schönste in der Welt.(This house is the most beautiful in the world.)Asien ist der größte unter den Erdteilen. (Asia is the largest among the continents.)
